So this was something I was interested earlier and what I did to fix accidently selecting the incorrect option was separate the two process, rebinding "Use selected action" to my Tab Key, and removing middle mouse from this option. My Action menu now works like this: I scroll up and down to 1. Open the Action menu and 2. Highlight the Action I want to complete. I then use my Tab key to Perform the Highlighted action. Should I need to leave the menu like normal I can just right click to cancel out like the default. as a Side note I also Rebound Tab to "Perform Default Action" so I can run up to vehicles and what not, and just Tab to enter when the Seat Icon shows up.
